AI Technical Summary

⚠Technical Problem

Existing small batteries have unreliable protection structures designed for compact spaces, poor heat dissipation, easily damaged control chips, and a risk of protection failure during short circuits.

⚗Method used

The power switch is integrated on the control chip, and the protection board is designed on the positive terminal of the battery. The control chip and power switch are wrapped in an insulating plastic encapsulation. The protection board is smaller than the surface of the positive terminal and has a fan-shaped structure. The connecting piece is designed to increase the heat dissipation area and reduce the internal resistance.

🎯Benefits of technology

It improves battery heat dissipation efficiency and safety, extends the lifespan of control chips and power switches, enables faster triggering of protection mechanisms, reduces production costs, and prevents dangers caused by short circuits.
